J . E . JONSSON STORY FOR COMMERCIAL &: FINANCIAL CHRONICLE

President J . E. Jonsson of Texas Instruments Incorporated, Dallas­ based electronics and geophysics firm , forecasts another highly successful year for 1956 .

Tl sales volume reached an a ll -time high of approximately

$28 ,500, 000 in 1955 . its 25th anniversary year . Mr . Jonsson expects that dollar volume will probabl y set a new record in 1956, with earnings above

the very satisfactory level of 1955 . '' The programs of the world's major oil producing companies indicate that the trend to foreign geophysical exploration for petroleum will continue , 11 he sai.d .

The geophysical exploration activities of Texas Instruments , con­

ducted through Geophysical Service Inc . and its worl d-wide affiliates , set a new record in 1955 . with most of the increase accounted for by foreign operations . Mr . Jonsson stated that the effectiveness of skilled personnel must be increased to explore these large new areas .

11

Seismation" -- the application

of automatic electronic instruments and techniques to seismic exploration will fill this need to the benefit of both exploration and instrumentatio n. Texas Instruments' geophysical instruments are manufactured by subsidiary H () uston Technical Laboratories .

"The trend to transistorization of electronic equipment, now firml y established. will result both in increased sales of semiconductor products and expanded activity in commercial and airborne electronics systems design and manufacture , " Mr . Jonsson said .

''In the electronics indus -

try, 1955 will go down as the year in which the long-heralded transistor be­ gan to find widespread commercial application. 11

Semiconductor Products division sales -- of which transistors were

the dominant factor -- were up over 30 0o/o in dollar value last year . Texas Instruments has firmly established its nationwide lead in transistor development and manufacture , with its germanium transistors being used in the majority of the brands of transistorized radios now in production . At year end , for the second straight year , it remained the exclusive commercial source for high temperature silicon transistors . "Sales were up in most Texas Instruments divisions in the year just past, 11 Mr . Jonsson continued, "and l can see no reason why this trend will not

continue .

Contracts already on hand promise another high level year for

our Apparatus division, where military electronics equipment is manufac­ tured, and this should also be reflected in the sales of our Components division . " Current military backlog is some $14, 000 , 000, about the same amount a.s last year at this time .

The Components division, which manufactures

t he basic .,building blocks '' for electronics systems, will be operating from

a broadened base for a ll of 1956, since it is now in production on carbon

deposited precision resistors . "With all foreseeable factors operating in a positive direction , we forecast a very successful -- perhaps record - breaking year in 1956 for the electronics and geophysics industries and Texas Instruments , 11 Mr . Jonsson

FOR JANUARY 15 RELEASE

TEXAS INSTRUMENT S EXPANDS, SETS NE.W RECORDS Sales at Texas Instruments Incorporated, Dallas-based electronics and geophysics firm, reached an all-time high of approximately $28, 300, 000 in 1955, its twenty-fifth anniversary year. of $24,400,000 in 1954.

This figure is compared with sales

All divisions of the firm contributed to the rise in

sales, with geophysical exploration and transistor manufacture showing especially noteworthy gains. OIL EXPLORATIO N HITS NEW PEAK Geophysical exploration activities of Texas Instruments, conducted through Geophysical Service Inc . . and its worldwide affiliates, set a new record.

Expansion in foreign operations accounted largely for the increase.

Gravity-magne tics survey operations, first offered as a standard GS! service in 1954, were expanded early in 1955.

The firm I s acquisition of

Rogers Exploration Service in October further enlarged gravity exploration activities. GS! entered 1956 with 65 seismic and gravity field parties, of which 15 were added in 1955.

It is believed that this number of field parties makes

it the world's largest supplier of geophysical services.

In addition to U.S. geophysical work in 1955, GS! parties were at work in petroleum exploration in Canada, Mexico, Colombia, Venezuela, Peru,

Its 405-ton marine geophysical

vessel, the 11 Sonic 11 , operated during the year in Eastern Hemisphere waters . GSI completed a round-the - world managerial organization in 1955 with opening of new regional offices in Cairo, Egypt; Calcutta, India; and Perth, West Australia .

Domestic offices were continued in Houston, Denver,

Shreveport, and Bakersfield , California . TRANSISTORS INV ADE CONSUMER MARKET In the electronics industry, 1955 will go down as the year in which the long-heralded transistor began to find widespread application in commercial products .

Texas Instruments firmly established its nationwide lead in

transistor development and manufacture, with its transistors now used in over 85% of the brands of transistorized radios coming off production lines at year -end . Semiconductor Products Division sales--of which transistors are the dominant factor - - were up over 400% in dollar value in 1955.

The Dallas firm

is now the largest producer of germanium radio transistors and the exclusive commercial source for high temperature silicon transistors.

A substantial

expansion of the main p l ant was completed in 1955 and is now occupied largely by semiconductor manufacture.

Texas Instruments Incorporated Page 3 ELECTRONICS OUTPUT CONTINUES HIGH Through its Apparatus Division, Texas Instruments continued to expand its activities in the design and manufacture of military and commercial electronics systems.

TI-built detection equipment continues to aid the

guarding of the nation against attack by enemy aircraft, ship, or submarine. Current military backlog is $14, 500, 000, a substantial increase over this time last year. In addition to the production and design of conventional military radar, sonar, and magnetic air detection systems, the transistorization oi military equipments assumed major importance in 1955 .

Transistorization reduces

size, weight, and power demand and at the same time increases reliability. TI' s position as the leading transistor manufacturer with wide experience in semiconductor circuit design, makes it ideally suited to transistorize both military and commercial electronics equipment. The Components Division--which designs and manufactures the basic "building blocks" of electronics circuits- -in 1955 also expanded its operations. Texas Instruments purchased the assets of the Radell Corporation, a precision resistor firm, and consolidated them with the Components Division at the 6110 Lemmon Avenue plant.

This division now has resistors, transformers,

and capacitors as its basic products.

(more)

Texas Instruments Incorporated Page 4 PLANT & SALES EXP;ANSIONS UNDER WAY The Petroleum Instrumentation Division, Houston Technical Laboratories, also had a year of increased sales . . Several new geophysical instruments and systems were added to the line and research, development and manufacture increased to the point where construction was begun on a 40, 000 sq. ft. new building for HTL on Buffalo Speedway in Houston. Marketing activities entered a new phase in 1955 with the opening of region offices staffed with representatives of the various manufacturing divisions in Los Angeles, Chicago, and New York.

HTL opened a branch

office in Calgary, Alberta, and branch offices were continued in Dayton and Washington for TI. Texas Instrw:nents Incorporated ended the year with over 2, 800 employees, another new record, and with over a quarter of a million sq. ft. of plant floor space in Dallas.

Two hundred fifty acres have been

purchased on the North Central Expressway for future expansion. PRESIDENT'S 1956 FORECAST President J.E. Jonsson forecasts another highly successful year for 1956, with dollar volume again setting a new record and earnings above 1955' s high levels.

Geophysical exploration will increase still further with

the trend to foreign exploration continuing.

SOUTHWESTERN MEDICAL SCHOOL RECEIVES TEXAS INSTRUMENTS COMPUTER A Medical Analogue Computer desigm:d and built by Texas Instruments Incor p orated today was formally accepted by the Southweste:i:-n Medica l School of the University of Te x as.

The custom-built "electronic brain" was received by the Drs. Donald Seldin,

de p al"tment head, and Prof. Leonard Madison of the department of Internal Medicine o:f the local medical school. Dr . Gordon K. Teal, assistant vice president in charge of the Research division of the Dallas-based electronics and geophysics firm, officiated at the presentation ceremony.

The eight-foot tall com~:>Uter resulted from a mathematical solution to a

s e~·ific medical diagnostic problem by Dr. Ross Macdonaid, director of the solid stat 8 physics r esearch de partment of Texas Instruments and clinical associate u rofessor of me .: ·i,-::::, i electronics at the Southwestern Medical School. The need for this comouter to make ra?i d c:i :.gn osis of abnormal fluid volumes in the body by the radioactive tr a c e r method resulted from a clinical research study at Southwestern Medical School.

It was conceived and designed by Dr. Macdonald and was

constructed at Texas Instruments under his close su? ervision. This cooperative effort resulted in Dallas receiving a new and valuable research tool for a small portion of the normal cost for such complex devices. The "first of its kind" com::lUter has not yet been given a name and will remain in the Te x :-:'.s Instruments Research division while school p ersonnel familiarize themselves \n i:h. i~ .:,; o p eration characteristics.

page 2 grown-diffused simultaneously at both the main Dallas plant and at the Radio Engineering Show in New York.

This entirely new technique has not been previously described in

electronics industry announcements of laboratory research, which are ordinarily years ahead of actual production. Officials of the Dallas-based electronics and geophysics firm described the new technique as based on the principles of solid state diffusion, wherein an ultrathin base layer (analagous to the vacuum tube grid) is produced by the migration of added impurity atoms while the semiconductor crystal is being grown.

This

method of making transistors relies on precise control of temperature and other factors. Texas Instruments regards the new ''grown-diffuse d" technique as its most \_,,'

significant transistor ''industry fir~t" to date.

Two earlier extremely significant

"industry firsts II by TI were the commercial production of silicon transistors break:­ ing through the temperature barrier and mas a-produced germanium rf transistors ' which, by breaking through the cost barrier, made possible the fir st commercially

available all-transistori zed radio receiver over 18 months ago. Dr. Gordon K. Teal, co -developer of the grown junction transistor and assistant vice-president in charge of the Tl l{esearch division, gave credit for the invention of the 11 grown-diffqsed 1' technique to Dr. Willis A. Ac:lcock, direc- . tor of the materials and component~ research department.

Dr. Adcock and

Boyd Cornelison, in charge of devic:e development for the Semiconductor Products division did the major development work in applying the technique to production devices. (more)

NEW PRODUCT NEWS RELEASE

NEW LIGHTWEIGHT RESISTIVITY SYSTEM ANNOUNCED BY HTL A new Resistivity System has been announced by_Houston Technical Laboratories, providing a fast and economical means of prospecting for mineral deposits and geological structures. The resistivity method is useful in the location of sulfide ores, water, geologic faults, and_other anomalies characterized by abrupt changes in electrical resistance. The method is comparatively old and well known; however, the added range and accuracy of the HTL Resistivity System attaches .new importance to ~ts practical application• . The HTL Resistivity System consists of two separate and distinct instruments, the Signal Generator Bank and the Voltmeter Bank. Although mechanically similar - - each has three panels mounted in identical watertight aluminum cases -- the two function quite differently. The determination of ground resistivity requires the measurement of a length, a current, and a potential.

Four electroq~s are placed in the

ground at equal intervals in a straight line. The Signal Generator Bank provides a 10 cycle square wave voltage which is appli,~d to the two outer (current) electrodes. The Voltmeter Bank is a potentiA,l measuring device and is connnected to the two inner (potential) electrQdes,

observation of current and potential enable the resistivity for a particular electrode-separation to be calculated. Althoqgh designed, for use with the Wenner Electrode Configuration which employs two current electrodes and two potential electrodes as described above, the HTL system may be readily adapted for use with the Lee Configuration which employs two current electrodes and three potential electrodes. The Signal Generator Bank consists of a signal generator, ammeter, storage batteries, and 11 B 1' batteries.

Direct current from the batteries is

metered before being converted into a 10 cycle square wave by the motor­ driven commutator. Output voltages are 22. 5, 45, 67. 5 ftnd 90 volts.

A

mercury cell provides a known voltage to check the voltmeter calibration. Meter ranges are 0 to 0. 0001, 0. 0003, 0. 001, 0. 003, 0. 01, 0. 03, 0. 1 and 0. 3 amps, full scale. (The meter range may be extended to 1 or 3 amps full scale by the use of external shunts. ) The accuracy is 2% full scale. The Voltmeter Bank measures the voltage between the potential electrodes and consists of a high gain calibrated amplifier together with necessary batterie& for portable operation.

The voltmeter, spare parts,

and storage batteries for the tube filaments are mounted an panels, with the 11 B" batteries in the bottom of the case.

Voltmeter ranges are Oto 0. 000;3;

0 . 0Ql, 0. 003, 0. 01, 0. 03, 0. 1, 0. 3 and 1. 0 volts full scale. full scale. (more)

FOR IMMEDIAT E RELEASE

TEXAS INSTRUME NTS PRESIDEN T PREDICTS 1956 WILL BRING NEW SALES AND EARNINGS RECORD

DALLAS, April 18 -- (Special) - - T e xas Instrument s President J.E. Jonsson predicted 1956 will bring new record highs in sales and earnings for his company.

Speaking at the annual stockholde rs' meeting at the· Company's main plant in Dallas, Mr. Jonsson estimated that 1956 Tl sales will approxi ­ mate $40,000,00 0, an increase of almost 40% over last year's record high of $28, 684, 6-53.

Earni ngs are expected to be greater proportiona tely,

After-tax earnings in 1955 were $1,581.790 , the best in.the 25-year history of the Dallas - based electronics and geophysics firm, Net i ncome per share of common stock was up 25% from 40¢ to 50f, he reported to stockholde rs.

Mr. Jonsson expects a substantial portion of the predicted . sales increase to come from the rapidly expanding semiconduc to:r markets for t}le tiny and effective germanium and s ilicon diode s ,and transistors in whose design and manufactur e Texas Instrument s has achieved industry leadership.

Page 2 Texas Instrument s

1955 sales of TI semiconduc tor products quadrupled from the preceding year.

The Company's germanium transistors are now used in

more than half the transistoriz ed radios in production.

For the second year

TI remained the only supplier of commercia l quantities of "high temperatur e" silicon transistors and diodes used in military electronics .

Last month the

Company announced developmen t of "grown diffused germanium and silicon transistors 11 with excellent, frequency characteris tics in the 200 megacycle band and with the ability to oscillate at 450 megacycle s.

Quantity production

of these transistors will make their use possible in high frequency communi ,, cation devices used by the military, missile guidanc e systems, and , when prices reach appropriate levels , television.

While this might seem to make

new and substantial inroads in vacuum tube markets, it is thought that the many new fields in which transistors may be used will produce enough additional vacuum tube bus i ness to avoid serious reductions in their market .

Mr . Jonsson announced that a 35 , 000 square foot addition to th e L e mmon A ve nue plant in Dallas was under constructio n for use by the Semi conductor Products Division .

He also announced plans for constructio n of a

new 15 0 , 000 square foot plant for semiconduc tor operations to be begun late in 1956 .

-

The new buildi ng is to be the first of a series to be built on the 250 -

acre tract acquired last year on the northern edge of Dallas .

The C o m pany 1 s

rapid growth made acquisition of a new and spacious site mandatory .

TI

will continue to us e the present plant for military and other production as well as to house administra ti ve and field servi ce functions of its wholly - owned

Page 3 Texas Instruments

exploration subsidiary, Geophysical Service Inc.

Activities of another

subsidiary, Houston Technical Laboratories, are to be moved into a new plant scheduled for completion in Houston, Texas, in June, 1956.

In addition to expanded semiconductor business, Mr. Jonsson also reported an increase in backlog of military electronics contracts to $14,000,000, up approximately $1, 000 ~000 from the same period last year.

La st year I s all-time high volume records set in geophysical exploration and instrumentatio n sales are expected to be exceeded in 1956.

Activities of the

Components Division, manufacturing such products as transformers ~ precision resistors ahd indicating meters, are likewise expected to improve during 1956.

Over-all, · the Company expects to offer numbers of new pro ­ ducts and services during 1956 which should broaden its markets in established fields and create a number of new ones .

In the

future, this growing line of recorders will be produced and marketed by HTL, the Instrument ation subsidiary of Texas Instrument s.

Recorders

Called the Dual Recording Milliamme ter, the unit

was originally developed to perform a critical function in a Tl-built airborne military electronics system.

It utilizes the magnetic fluid clutch principle

to produce sensitive, accurate recordings under extremes of vibration and shock. Only last month, another revolutiona ry new type ink writing recorder was commercia lly announced.

Called the Rectilinear Recording Milliamme ter,

this new instrument is the first galvanome ter -actuated recorder to present data in true rectilinear fashion.

Previous recorders of this type have dis-

tarted signal waveforms by curvilinear reproductio n caused by the recording pen pivoting from a fixed axis. The Rectilinear Recording Milliamme ter utilizes an exclusive panto­ graphic linkage to allow the writing pen to present data in the same rectilinear fashion as it would be charted graphically or would appear on atl os cillographi c recording.

This simplifies interpretati on, measureme nt, and data reduction

and it is anticipated that the unit has very great market potential.

SHORT PULSE BLASTER ANNOUNC ED BY HOUSTON TECHNICA L LABORATO RIES A new precision seismic blaster , providing a high degree of accuracy in the inducement of application time breaks, is announced by Houston Technical Laboratori es. Called the Short Pulse Blaster, this new detonator gives positive firbg action within a highly restricted period of time.

A high current is

su-stained for 0. 3 millisecond s and then reduced sharply to zero within 0. 2 millisecond s. Since the cap must fire during this period, the application time break inaccuracy is confined to 0. 5 millisecond s. The Short Pulse Blaster consists of two separate units housed in the same case, secured by Dzus fasteners for easy removal.

They are the

Pulser unit and the Time Break unit. The Pulser unit consists of circuitry for the Cap test, the Charging switch, and the Firing switch . The Cap test terminals connect the cap to a 1-volt silver chloride cell through a ruggedized 0-10 ma. meter.

The meter reading will indicate

the condition of the external cap circuit- -whether normal, open, partially open, or shorted.

A rheostat makes it possible to use the circuit for varied

cap circuit lengths and combinatio ns.

The current in the silver chloride cell

is self-limite d below the cap firing level .

(more)

page 2 HTL short pulse blaster

The Charging switch connects the 90 volt battery supply to the tantalum capacitors.

An indicating lamp lights up approximately 1 / 2 second after

switching when the capacitors are charged to the firing level. A resistor insures a discharge path for the capacitors .

If the cap does not fire imme­

diately, releasing the spring tension Charge switch will discharge the capacitors almost fnstantly. The Firing switch connects the capacitors across the cap. The 90 volt level is held for 0. 3 milliseconds by an inductance coil, and then drops off sharply to zero voltage within 0 . 2 milliseconds. The firing operation may be performed with one or two hands . At the instant of firing, a pulse is received in the Time Break unit . A selected portion of the voltage appears at the LINE-T. B . terminals to provide a Time Break signal to the recording oscillograph or the magnetic recorder , as desired .

The typical Short Pulse Blaster includes an application

type Time Break unit.

This may be removed entirely or replaced by a custom

time break unit, a radio-controlled firing system, or a remote-start system for the camera . The Time Break is induced--not wired directly to the firing circuit.

Low capacitance of the circuit keeps cross-feed to a minimum.

Being an application type time break, it does not pick up noise from the cap leads . Designed for all weather performance, the Short Pulse Blaster operates e ff iciently from+ 150° F

t o -40°P .

Below the freezing point ~ mercury

page 3 HT L short pulse blaster

batteries are recommended .

The circuitry, wooden case, and bakelite

panels are all designed to increase the safety factor .

The hardwood case

is waterproof glued throughout , with a synthetic rubber seal between the case and lid complet ing the watertight construction.

The lid is held by an

8 11 hinge and two sets of strikes and catches, with a smooth hinged handle on top .

Compatt (9-5/ 16 x 9-5/ 16 x 10 inches) and weighing only 12-3/4 lb,

the Short Pulse Blaster is precise, portable and durable. The Short Pulse Blaster is manufactured by Houston Technical Laboratories , Instrumentation subsidiary of Texas Instruments Incorporated.

1500-VOLT SINGLE JUNCTION SILICON RECTIFIERS ANNOUNCED BY TEXAS INSTRUMENTS

Five production types of radically new silicon rectifiers- -featuring a single grown junction element with 1500-volt breakdown voltage - -are announced by Texas Instruments Incorporated, leading manufacturer of transistors and other semiconductor products.

In the past, rectifiers that approached the voltage ratings of

these unique TI single junction devices were forced to utilize several lower voltage cells connected in series . Now, for the first time, 1500-volt single junction miniature rectifiers are in production and immediately available with stable operation up to 150° C and forward current ratings up to 100 ma! These new rectifiers are expected to have wide application wherever there is a need to miniaturize high voltage power supplies. Available in two types of axial and stud half-wave models and a full-wave plug-in model, these hermetically sealed rectifiers eliminate the need for filament power.

The axial •models, 1N543 and 1N543A, allow point-to-point wiring;

Types 1N544 and 1N544A are stud-mounted for maximum heat dissipation.

The

plug-in model, TI/680, can be used in many applications to rep:a ce the JAN 6X4 rectifier tube.

GRAVITY ANOMALY SIMULATOR ANNOUNCED BY HT L The Gravity Anomaly Simulator --a new instrument that simulates the effect on the earth's gravity field of a subsurface body of anomalous density--is announced by Houston Technical Laboratories, Instrumentatio n subsidiary of Texas Instruments Incorporated.

This compact instrument will be of

value in interpreting data obtained when prospecting for petroleum and mine rals with gravity meters, of which,HTL is the leading producer . With the new Gravity Anomaly Simulator, it is possible to prepare gravity data in hours that would require days by previous calculating methods. The instrument, measuring 24 x 19 x 31 inches and weighing only 24-1/2 lb, can be operated on an ordinary office desk . The Anomaly Simulator has two basic applications which are highly useful in the processing of $r,avity data :

1. Starting with a ppssible sub­

surface body, the gravity anomaly that 1t would produce may be calculated; and 2.

Conversely, having measured a gravity anomaly, subsurf~ce_bod ies that

may produce such an q.nomaly may be simulated . The HTL Gravity ,Anomaly Simulator utilizes the principle of Lambert's cosine Q law . Mathematically , it may be shown that the light integral for a

page 2 gravity anomaly simulator horizontal layer has the same form as the gravitational integral for the same By suitably scaling down all dimensions of the gravitational layer,

layer.

a luminous surface of the same shape can be formed, allowing the integration to be performed by simply measurmg the illumination .

In the HT L Anomaly Simulator, an opaque slide of paper having a cut-out opening in the outline of the desired body is placed over a light source.

The

light reading is shown on a meter and combined with a multiplicative factor m determining the gravitational anomaly. Basically, the new HTL Gravity Anomaly Simulator consists of a light source and measuring device .

The light source is an incandescent bulb

located beneath two layers of flashed opal glass.

This provides a surface

which approximately obeys Lambert's +aw. Over this an opaque paper is placed which has a cut-out hole the same shape as the outline of a layer of the desired body. The light measuring device is a photocell . The output of the photo­ cell, which is proportional to the incident light,· is amplified by a duo-triode difference amplifier and read on a meter. The photocell is mounted on a cross-arm which, in turn, is mounted on a vertical column so that a traverse may be made with a cut-out at any practical depth .

By moving the cut-Out on the table, offset traverses may be made

easily .

NE .W AXIAL LEAD, GLASS ENCAPS ULATED , HIGH CONDUC TANCE SILICON DIODES ANNOUN CED BY TEXAS INSTRUM ENTS

Four new types of h i gh conduc tance silicon jun~tion diodes for use in precise signal rectificat ion are announce d by Texas Instrume nts Incorporated, leading manufac turer of semicond uctor devices and electroni c systems.

These new diodes will have wide applicati on in circuits requir -

ing high, uniform forward currents and extremel y low back currents at elevated temperat ures. At ambi e nt temperat ures of 150° C, all four types of these hermet ically sealed, miniatur ized units have forward current ratings of 25 ma and reverse currents of 30 ua .

At 25° C, they have 100 ma forward current

ratings and reverse currents of only 0. 1 ua.

These high forward currents

are ccmplete ly independ ent of breakdow n voltages!

Types 660 through

663 have peak reverse voltage ratings of 30 , 70, 150, and 200 volts respectiv ely . These silicon junction diodes are especiall y desirable for applicati ons in networks , modulato r s , and demodul ators because of their uniform design characte ristics .

Their extremel y h i gh forward currents make them particu -

larly a dvantag e ous for us e i n magneti c a mplifie r s and compact power supplies . (mor e )

Use of these uniform, h i gh conductance, silicon diodes will substantially increase system reliability i n applications where heat, shock, and vibra­ tion are major cons i derati ons . All units are glass encapsulated to insure complete protection against moisture and humidity and are axial constructed to allow point - to-point wiring.

Each type weighs only 0. 16 gram and is 100% tested to meet speci­

fied design characteristics. The addition of these four new types of high conductance diodes increases to 59 the number of silicon junction diodes now be i ng manufactured by Texas Instruments.

These include general purpose, voltage reference,

and high conductance diodes. For Bulletin DL-S 614, containing complete design data and character istic curves, write to Texas Instruments Incorporated, 6000 Lemmon Avenue, Dallas 9, Texas.
